Different Types of Exit Signs: Illuminated, Non-Illuminated, LED, and More

Exit signs play a critical role in guiding occupants safely out of buildings during emergencies. Choosing the right type of exit sign can significantly impact visibility, reliability, and compliance with safety standards. Here’s an overview of the most common types of exit signs used today:

1. Illuminated Exit Signs

Illuminated exit signs contain built-in lighting sources such as fluorescent bulbs or LEDs. They are designed to remain visible in both normal and power outage conditions, often supported by backup batteries. These signs provide bright, consistent illumination making them highly reliable in emergencies.

Advantages:

• High visibility in low light or smoke-filled environments

• Meets most fire safety and building codes

• Long-lasting lighting options like LEDs reduce maintenance

2. Non-Illuminated Exit Signs

Non-illuminated exit signs rely on external lighting to remain visible. Typically made from reflective materials, they depend on ambient light sources such as emergency lighting or daylight. While less costly upfront, they may be less effective during power failures or dense smoke.

Advantages:

• Lower initial cost

• Suitable for well-lit environments

• Easy to install and maintain

3. LED Exit Signs

LED exit signs are a subtype of illuminated signs that use Light Emitting Diodes (LEDs) as the light source. LEDs are energy-efficient, have a long lifespan, and provide bright illumination. They also allow for slim, lightweight designs and are increasingly popular for modern buildings.

Advantages:

• Energy-efficient and eco-friendly

• Low heat emission and high durability

• Reduced maintenance and operating costs

4. Photoluminescent Exit Signs

Photoluminescent exit signs absorb and store ambient light, then glow in the dark without any electrical power. They are often used as a backup in case of power loss. These signs are maintenance-free and environmentally friendly but require sufficient light exposure to “charge.”

Advantages:

• No electricity required

• Reliable in power outages

• Eco-friendly and low maintenance

5. Combination Exit Signs

Some exit signs combine multiple technologies, such as LED illumination with photoluminescent backup, ensuring maximum visibility and reliability under all conditions.

Conclusion

Selecting the appropriate exit sign depends on your building’s layout, lighting conditions, and compliance requirements. Illuminated and LED signs offer consistent visibility, while photoluminescent signs provide reliable backup without power consumption. For tailored solutions that meet your safety needs, consult a trusted exit sign manufacturer.
